Point-Slope Form And Slope-Intercept Form Worksheet With Answer Key

Point-slope form:

- formula used to find the equation of line given a point that the line

passes through, and the slope of the line

- derived from the slope formula

∆��

o slope is �� =

∆��

= �� ( �� − ��

)

o point-slope form is ∆�� = �� ∙ ∆�� or �� − ��

- ( ��

) represent the point that the line passes through and ��

, ��

represents the slope of the line

Slope-intercept form:

- way of expressing the equation of a line by isolating the �� variable

and listing the slope of the line �� and its ��-intercept ��

- found by taking point-slope form and getting �� by itself

o �� = �� + ��

o this means expressing �� in terms of ��

- slope-intercept form can also be found directly by simply identifying

the slope of a line and its ��-intercept

To find the equation of a line, you need the following information:

- either one point that the line passes through and the slope of the line

o find the equation of the line using either slope-intercept form or

point-slope form

- or two points that the line passes through

o find the slope of the line using the two points

o use the slope and either point to find the equation of the line

using either slope-intercept form or point-slope form
